BUBBLE-BLOWER.

SPECIFICATION forming part of Letters Patent No. 650,324, dated May 22, 1900.

, Application tiled January 3l, 1899. Serial No. 704,053. (No model.)

To all whom, it may concer-r2,.-

Be it known that I, PETER D. IIORTON, a citizen of the United States of America, residing in the city of Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Bubble-Blowers, of which the following is a speciiication.

This invention relates to an improvement in bubble-blowing devices of the kind or description which are constructed to form one bubble inside another; and the same consists lin the construction and combination of parts,

as hereinafter described, and specilically pointed out in the claim at the end of this specification, reference beinghad to the drawings forming part thereof.

Figure l of the drawings is a perspective view of a bubble-blower constructed in accordance with my said invention. Fig. 2 is a view in longitudinal section. Fig. 3 is an end View from the front. Fig. 4 is a slight modification in which the central plug and inner tube are formed integral.

This device is composed of a hollow cylindrical body A,havinga tubular stem or mouthpiece B, of smaller diameter, fixed in line with the longitudinal axis of the cylindrical body, and a cylindrical tube C, of smaller diameter than the cylindrical body, fixed in the center of the body substantially in line with the bore of the mouthpiece and extending longitudinally through the center of the cylindrical space. This center tube should be set concentrically with reference to the surrounding cylinder, and in length it should exceed that of the cylinder from the end where it is united to the cylinder outward to the opposite end, so that its outer end will project a short distance beyond the rim of the cylinder. In one way I secure this central tube in place within the cylinder by iixing one end of the tube in a plug D, which, being fitted tightly into 4the cylinder, is fastened in place by any proper means, such as by drivinga small pin dx from the outside through the body of the cylinder and into the plug, or in another way I form the plug integral with the tube C, as

shown in Fig. et, and then after inserting this piece in the cylinder to the proper distance, so that the free end of the stem will project beyond the edge or rim of the cylinder, I se. cure the same in place by the means before described to fix the inner tube in the desired central position within the surrounding cylinder. v

Both in the case of the plug C and of the modification last described contracted passages OX C are made through the body of the plug or between the surrounding wall of the cylinder and the plug that closes the cylinder-space at or around the end of the inner tube. These passages serve to connect the air passage or space bx behind the plug with the cylinder-space b lyingin front of the plug and around the central tube. Thron gh these passages air is supplied and carried from the mouthpiece into the main cylinder-space to form a bubble from the film adhering to the rim of the large tube or cylinder, while at the end of the central tube abubble is formed at the same time. The cylinder and the tube being set concentrically the inner bubble is detached at all points from the walls of the surrounding bubble, and when the completed bubble is loosened from the blower to float in the air the smaller bubble will be seen inside the larger bubble in a state of suspension. This condition is retained for a greater or less length of time, depending on the qualities of the soapy solution and the condition of the atmosphere, until the inner bubble is ruptured by contact with the surrounding walls of the larger bubble. Vhenever this contact takes place and the inner bubble is ruptured, a still smaller bubble is immediately formed within the remaining bubble, the transforma- .tion taking place automatically or entirely,

through the operation of natural laws, within the bubble.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The herein-described bubble-blower com= prising the hollow cylindrical body, a plug closing the interior space near one end, the

hollow stem of smaller diameter fixed in that In testimony that I claim the foi'egoing I end, the eentrally-xed tube in the plug exhave hereunto set my hand and seal. tendn loneitudinall throu0h the bod and A projecng leyond theyeud of:o the body7 and PETER D HORON [L S] 5 longitudinal air-passages through the plug IVitnesses:
